Spectra viewer

Powerful viewer to explore our large fluorophore database

You can find our Spectra viewer here.

Over the past years we have collected a large number of fluorescent spectra for 1-, 2- and 3-photon excited fluorescence. Our database contains additional fluorophore information (e.g. extinction coefficients, quantum yield, lifetime) for most of the fluorophores and provides a number of ways to display, select and compare the properties of various fluorophores. We have built an online spectra viewer that also provides access to a large number of spectra of optical components, such as light sources, filters and mirrors. Here is a list of some of the features of our spectra viewer:

  • The viewer uses a large database with more than 550 fluorophores and spectra of more than 250 optical elements (filters and mirrors).
  • The database contains two-photon excitation spectra for more than 50 fluorophores and we are planning on adding additional spectra in the near future.
  • Custom spectra can be uploaded and displayed along with the spectra contained in the database.
  • Plots can be displayed using normalized or absolute values on a linear or logarithmic axis.
  • In addition to the “standard” spectral plots the viewer interface contains a “2D viewer” in which excitation and emission spectra are combined into 2D contour plots. This is particularly useful when displaying excitation/emission spectra for various fluorophores simultaneously.
  • A large number of additional fluorophore properties are contained in the database and can be accessed through a fluorophore browser (a table with various search and filter functions) or visualized using a 2D scatter plot. Up to four properties can be visualized simultaneously using the marker’s x- and y-coordinates as well as their size and color.
